Description

  The present invention relates to a bird prevention system and a bird prevention method, and more particularly, to a bird prevention system and a bird prevention method for flying an airship using GPS (Global Positioning System) as a countermeasure against bird damage in a field. .

  In a conventional bird-proof system, for example, as described in Patent Document 1, a fixed repelling device (kakashi, animal model, etc.) is used as a measure against bird damage. Therefore, in Patent Document 1, in order to prevent the birds from getting used to these bird damage countermeasures, another bird damage is different from the currently implemented bird damage countermeasures. It has been proposed to periodically change to countermeasures at random.

  Thus, in the prior art, the bird protection system is a fixed repelling device (kakashi, animal model, etc.), and there is no one that prevents birds while flying.

  Hereinafter, embodiments of a bird protection system of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram (movement in a field) showing the configuration of a bird protection system according to Embodiment 1 of the present invention. The bird protection system of the present invention is intended to take measures against bird damage in a field by flying a flying object in a monitoring target area such as a field and dissipating birds flying in the monitoring target area. Therefore, in the following description, the operation of flying the flying object for the purpose of dissipating the bird is referred to as “bird-proof”. In FIG. 1, 1 is an airship (aircraft) configured to be able to fly in the air with an engine or a motor, etc., 2 is a GPS receiver mounted on the airship 1, and 3 is a processing unit mounted on the airship 1. Reference numeral 4 denotes a field A in the monitoring target area of the airship 1, and 10 denotes an example of a flight route of the airship 1.

  In the airship 1, first, position information of the field A4 in the monitoring target area is stored in a storage device (not shown) provided in the processing unit 3 of the airship 1. The position information is position information of latitude and longitude around the boundary of the field A4, and preferably includes information on a plurality of positions on the periphery of the boundary so that the area range of the field A4 can be grasped. If it is a substantially rectangular shape, only the position information of the four corners may be included, or the four corners and position information between them may be included. When the position information between the four corners is included, the position interval is arbitrary and may be set as appropriate (for example, 1 meter interval, 5 meter interval, etc.).

  The GPS receiver 2 of the airship 1 receives the current position information of the airship 1 from the GPS. The position information includes information on the latitude and longitude of the current position of the airship 1.

  As shown in FIG. 1, the airship 1 flies in the field A4. At this time, the flight route 10 first flies in a straight direction. Alternatively, only the initial flight direction may be set in the processing unit 3 in advance. In any case, the subsequent routes are randomly set by the processing unit 3 by a method described later. The flight altitude of the airship 1 gradually increases after the start of flight, but stops increasing when it reaches a certain preset flight altitude, and then flies at a substantially constant altitude. At the end, the altitude is gradually lowered and finally landing and stopping. Alternatively, the altitude may be changed periodically or randomly without flying at the constant altitude. Further, the flying speed of the airship 1 may be constant, or may be changed periodically or randomly. The control of the flight operation of the airship 1 is performed by the processing unit 3.

  During the flight, the processing unit 3 compares the latitude and longitude of the airship 1 acquired by the GPS receiver 2 with the latitude and longitude around the boundary of the field A4, and the latitude and longitude of the current position of the airship 1 is around the boundary of the field A4. When the vehicle goes out of the range of latitude and longitude, the direction of 90 ° + α is changed with the current flight direction as a reference (0 °). Note that the 90 degree direction is either 90 degrees right (90 degrees clockwise) or 90 degrees left (90 degrees counterclockwise). It is assumed that the processing unit 3 is set in advance. Also, the value of α is within 90 degrees (range from 0 degrees to 90 degrees). The airship 1 continues to fly after turning. At this time, if it is not possible to return to the range around the boundary of the field A4 by one change of direction, the change of direction is repeated as many times as possible until the return. Even if the airship 1 returns to the range around the boundary of the field A4 after the direction change, if the airship 1 goes out of the range around the boundary of the field A4 again, the direction change is performed again in the same manner. Do. The flight route 10a portion of the flight route 10 in FIG. 1 shows an example in which the direction is changed twice in succession because it cannot return to the periphery of the boundary in the field A4 by one direction change.

  The airship 1 repeats this operation to prevent the area within the boundary of the field A4. The flight route 10 of the airship 1 becomes a random route by setting the α value of “90 + α degrees” of the angle to change direction as a random number. In this way, the airship 1 can fly at random, thereby preventing birds from getting used to the airship 1. The random number may be generated by the processing unit 3 using a random number generation function of a computer (CPU) that constitutes the random number, but a random number table is stored in the storage device of the processing unit 3 in advance. Alternatively, it may be extracted from the random number table.

  As described above, in the first embodiment, as a countermeasure against bird damage, the airship 1 is caused to fly using GPS, and the position information of the field A4 in the monitoring target area stored in the airship 1 and the airship 1 obtained from the GPS. Compared with its own position information, when the airship 1 goes out of the area of the field A4 to be monitored, the direction is changed so that the airship 1 is returned to the area to fly and the birds are dissipated. did. In the conventional measures against fixed bird damage such as kakashi, there is a problem that the distance from the flying bird is far and the effect is small, but in this embodiment, since the airship 1 is used, the flying bird is used. The effect is sufficiently expected. Further, since the flight route 10 of the airship 1 is made random, it is difficult for the bird to predict the flight route of the airship 1, and there is a possibility that the airship 1 flies in an unexpected direction and the bird feels a threat. Expected to be many, high effect can be expected. In addition, when the airship 1 flies while confirming its own position by GPS and deviates from the monitored area, the direction change was repeated and the automatic return to the monitored area was made. It can be operated without an operator, has no trouble for the user (operator), and is highly convenient. In addition, since the airship 1 flies over the sky, it is convenient even if it is used during farm work, without hindering farm work.

  In the above description, the altitude of the airship 1 has been described as being altitude that may be constant altitude or periodically or randomly after altitude rise. However, altitude may be periodically or randomly changed. When changing, the upper limit and the lower limit of the flight altitude of the airship 1 are set in advance, and the altitude is changed within the range set by the upper limit and the lower limit. When the altitude is changed, it is more difficult for the bird to predict the flight route of the airship 1, and it is expected that the airship 1 will fly in an unexpected direction and the bird will feel threatened, and further effects will be obtained. I can expect.

  In the above description, an example in which the airship 1 flies while automatically changing the direction in the monitoring area has been described. However, the present invention is not limited to this, and a configuration in which a user (operator) can also perform remote operation with a remote controller is used. You may make it do. In any case, the flight start and flight end operations are performed by a user (operator) using a remote controller.

  In addition, the shape of the airship 1 (aircraft) is a substantially elliptical sphere shown in FIG. 1, but is not limited thereto, and may be a shape resembling an airplane or a helicopter, or a bird flying to the field A4 ( It may have a shape resembling the shape of another type of bird that is a natural enemy. As described above, the shape of the airship 1 may be designed freely as appropriate, and a flying body having an arbitrary shape can be used as the airship 1.

  In the above description, the example in which the direction of the airship 1 is changed only when the airship 1 goes out from the periphery of the field A4 has been described. Even when flying inside, the direction of the airship 1 may be changed at a predetermined cycle or a random cycle.

Embodiment 2. FIG.
FIG. 2 is a configuration diagram (movement between fields) showing the configuration of the bird protection system according to Embodiment 2 of the present invention. In FIG. 2, 1 is an airship, 2 is a GPS receiver mounted on the airship 1, and 3 is a processing unit mounted on the airship 1. Reference numerals 4, 5, and 6 are field A, field B, and field C to be monitored by the airship 1, and numerals 7, 8, and 9 are fixed positions in the fields A4, B5, and C6 (each field). Any point in A to C (for example, the middle of the field is designated by latitude and longitude). 11 is an example of the flight route of the airship 1.

  The second embodiment basically performs the same configuration and operation as those of the first embodiment. However, the second embodiment is different from the first embodiment in that a single airship 1 includes a plurality of airships 1. It is a point to protect birds in the field. Therefore, the airship 1 moves between the plurality of fields in a predetermined order set in advance and goes around. In other words, when the airship 1 is performing bird protection of one field by the operation shown in the first embodiment, when the predetermined time of “movement between fields” is reached, monitoring is performed. Suspend the flight in the middle field, move to the next field, and start bird protection in that field. In the second embodiment, the processing unit 3 stores in advance position information of the fixed positions 7, 8, and 9 in the field A4, the field B5, and the field C6. The fixed positions 7, 8, and 9 may be arbitrary positions in each of the fields A to C, and may be, for example, the middle position of each field, and are designated by the latitude and longitude of the position. The operation of the second embodiment will be described in detail below.

  First, the airship 1 flies along a random flight route 10 while automatically changing the direction by the method shown in the first embodiment, and performs bird-proofing of one of the fields to be monitored. Since the operation up to this point is exactly the same as in the first embodiment, detailed description thereof is omitted here. At this time, when the predetermined time “movement between fields” is reached, the airship 1 receives the current position information of the airship 1 from the GPS by the GPS receiver 2 installed. The flight route 11 is determined by finding the direction and distance for moving to the fixed position (any one of 7, 8, 9) of the next field registered in advance in the processing unit 3, and based on the result, The direction of the airship 1 is changed, and the airship 1 is moved to a fixed position (any one of 7, 8, 9) of the next field. Note that the flight route 11 in this case is basically the shortest distance (straight course).

  The time for “moving between fields” can be set arbitrarily, and when the set time has elapsed, the bird-proofing process in the field during the bird-proofing is interrupted and the moving process to another field is given priority. To do. Although described as “time”, actually, the monitoring time for one field is set in advance (for example, set to 10 minutes), and the elapsed time from the monitoring start time is set by the timer function of the processing unit 3. Measure, and when the elapsed time reaches the monitoring time, “move between fields” is performed.

  For example, if the airship 1 flies within the field A4 for 10 minutes to prevent birds, the direction and distance to move from the current position to the fixed position 8 of the next field B5 are obtained, and the direction change is made based on the result. And move to the fixed position 8 of the field B5. After the movement, the airship 1 flies in the field B5 for 10 minutes to prevent birds. Then, after 10 minutes have elapsed, the direction and distance for moving from the current position to the next fixed position 9 of the field C6 is obtained, the direction is changed based on the result, and the fixed position 9 of the field C6 is moved. . After moving, the airship 1 flies in the field C6 for 10 minutes to prevent birds. Then, after 10 minutes, the direction and distance for moving from the current position to the next fixed position 7 of the field A4 are obtained, the direction is changed based on the result, and the position is moved to the fixed position 7 of the field A4. Start bird protection in the field A4. This operation is repeated, and the field A4 → the field B5 → the field C6 → the field A4,...

  As described above, also in the second embodiment, the same effect as in the first embodiment can be obtained, and in the second embodiment, a plurality of fields 4 to 6 are provided for one airship 1. This is effective in terms of cost because it is set as a monitoring target and moved to the next field in order periodically to prevent birds. For example, one airship 1 can be jointly purchased by owners of a plurality of fields.
